Default Knocking on accelerate

So just picked up this 1994 Silverado for 900 bucks. Seems to run a little rich but that's not what I'm worried about. When accelerating past about 3500 rpms there is a slight knocking then when the trans shifts the noise stops. Wonder what the problem is.... Thanks in advance
